winding-spool and to traverse the cord from one end to the other of the spool, so that the cord will be laid uniformly thereon; and the object of my invention is to provide a winding mechanism capable of being rotated at a high speed by reducing the friction and maintainin g a perfect balance of the rotating parts, and I accomplish these objects by means of the mechanism hereinafter described, and shown in the accompanying drawings, in which-- Figure 1 represents-a portion of a twisting machine, showing one of the flier-frames and winding-spools inside elevation. Fig. 2 represents a portion of the traversing ring provided with a groove or guideway for the'traveler or cord-guide, said traversing ring being shown in transverse sectional view; and Fig. 3 represents a top view of the cord-guide or traveler removed from the traversing ring.

Similar letters refer to similar parts in the different figures.

The twisting-machine represented in Fig. 1 is of a usual and well-known type, comprising a rotating flier-frame consisting of the upper and lower heads A and A, connected on diametrical sides of the flier-frame by a pair of rods B B,known as flier-arms, said flier-frame being capable of rotation about a vertical axis by means of connected driving mechanism. Held concentrically within the flier-frame is a winding-spool C, upon which the twisted cord is wound, and surrounding the flier-arms B B is a ring D, attached to a bracket D, which is carried by the frame D capable of sliding vertically on a bar D which is attached to the framework of the machine and provided with a rack D which engages (No model.)

a pinion E, carried upon a shaft E, to which a reciprocating motion is imparted by means of a mangle-wheel F, attached to the shaft E and driven by a rotating star-wheel F, whereby a rising-and-falling motion is given to the frame D and ring D equal in extent to the space between the upper and lower heads.

of the winding-spool C.

The traversing ring D is provided with an L-shaped groove G, opening upon the interior of the ring and adapted to receive a cordguide or traveler H, preferably made of vulcanized fiber or similar material in order to reduce its weight and consisting of a plate H, running in the horizontal section of the L-shaped groove Gr, and having a vertical flange HF, running in the vertical section G of the groove. The horizontal portion H of the traveler H projects beyond the inner surface of the traversing ring vD and is provided with a notch I to receive one of the flier-arms B and with an eye J, through which the twisted cord at is conducted as it passes from the twisting mechanism to the winding-spool. The cord-guide or traveler H is of sufficient length only to receive the notch I and the eye J, and during the operation of the machine it is driven around the traversing ring D with great rapidity by the rotation of the flier-arm B, thereby winding the twisted cord around of the cord-guide in the groove of the traversing ring the cord is uniformly laidon the winding-spool by the rising-and-falling motion of the ring D through its connected actuating mechanism.

I am aware that it is not, new in winding mechanisms to provide a cord-guide capable of rotating around the winding-spool in a grooved ring to which a traversing motion is imparted, and I do not herein claim such broadly.- In winding mechanisms of this class, however, great difficulty is'experienced in preserving a proper balance of the rapidlyrotating parts and in reducing friction due to the pressure of the rapidly-rotating cordguide upon the walls of its guideway. The friction of the cord-guide is increased by the centrifugal force due to its weight and rapid rotation and also by the pull or strain exerted upon the cord-guide by the tension of the twisted cord. Owing to the difficulty of properly lubricating the groove or guideway containing the cord-guide, it has been found necessary to adopt various expedients to reduce the friction upon the cord-guide, to maintain a perfect balance of the rapidly-rotatin g part, and to properly resist the pulling strain exerted by the cord as it passes through the eye of the cord-guide. These results have heretofore been accomplished by placing the eye of the cord-guide in a continuous rotating ring held within the groove of the traversing ring and also by constructing the cordguide with a sleeve fitting one of the flierarms. The former method necessitates the use of a large continuous metallic ring having an accurate fit throughout its entire contact with the traversing ring and of suiiicient Weight to render it rigid, with a large surface in contact with the guideway, and requiring constant lubrication to prevent its heating while running at a high rate of speed. The attachment of the cord-guide to a sleeve accurately fitting and capable of sliding on one of the flier-arms and having lugs engaging the annular groove in the traversing ring obviates some of the objections to a continuous rotating ring; but as the eye of the cord-guide must be located upon one side of the flierarm inclosed by the sleeve the tension of the cord tends to rotate the sleeve upon the flierarm, which requires a spline connection between the ring and flier-arm, thereby increasing the frictional surface in contact and the expense of construction. My present invention overcomes these several disadvantages by making the cord-guide as short as possible andof light material, such as vulcanized fiber, andresisting the tension or pull of the cord by means of a flange H on the cord-guide, which is inclosed within the L-shaped slot of the traversing ring. The tension of the cord is also partially overcome by the centrifugal force exerted by the cord-guide, which tends to throw the cord-guide radially outward and in opposition to the tension of the cord, which tends to draw the cord-guide radially inward. I thereby obviate the necessity of employing a'continuous ring containing the cord-guide in order to counterbalance the opposite sides by causing the tension of the cord and the centrifugal force to counterbalance each other. The cord-guide is rapidly and cheaply made, is easily replaced when worn, and is capable of being rotated at a very high speed Without lubrication of the guideway.

That I claim as my invention, and desire to secure by Letters Patent, is

1. In a winding mechanism, the combination of a rotating flier-frame and a Windingspool held concentrically therein of a ring inclosing said frame and lying in a plane at right angles with its axisof rotation, said ring having on its inner side an L-shaped groove, actuating mechanism by which said grooved ring is given a reciprocating motion the length of the winding-spool, a traveler consisting of a short plate provided on its outer edge with a flange with its flanged edge inclosed in said L-shaped groove and having an eye or cord-guide with the inner edge of said traveler engaging said flier-frame, substantially as described.

2. The combination with a winding-spool and a flier-frame having an arm parallel with its axis of rotation, of a traversing ring provided with an L-shaped groove, means for imparting a traversing motion to said ring, a

traveler consisting of a short plate with an eye or cord-guide and engaging said flier-arm and a flange on the outer edge of said plate and at right angles thereto, said flanged edge being inclosed in said L-shaped groove, sub stantially as described.
